Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of encoders, in particular to an encoder code disc installation component. Background Art
[0002] A motor encoder is a device used to measure the rotational position and speed of a motor. It is usually integrated on the motor shaft, and uses internal sensing elements to capture the shaft's rotational motion and convert these motions into electrical signal outputs, which can be read and processed by external devices to achieve precise control of the motor's motion state.
[0003] For example, the Chinese utility model patent disclosed by publication number CN206481183U: a hollow motor shaft assembly, in which the encoder code disk is installed on the motor shaft, and the reading head reads the encoder code disk information in a photoelectric form after the encoder code disk is calibrated, and then the deep groove ball bearing is pressed against the encoder code disk. This method directly uses the pressure of the bearing on the code disk to fix it on the motor shaft. However, in this installation method, when the motor shaft drives the code disk to rotate, if the bearing is improperly installed or there is a manufacturing error, it may cause the concentricity of the code disk and the rotating shaft to be poor, that is, the loose fixation of the code disk and the rotating shaft may cause errors in the encoder reading, which will cause errors in the encoder measurement and affect the control accuracy of the motor. In addition, when the motor shaft rotates at high speed, the centrifugal force and the inertia of the motor start and stop will cause the bearing to loosen, so that the code disk cannot operate normally.
